Airplane mode is a setting on your realme phone which disables its wireless communication abilities, theoretically making it approved for using on aircraft or where the wireless functions are forbidden.
Go to [Settings] > [Airplane Mode] and tap the slider to turn it on. You can also swipe down from the top of your screen to open Control Center, then click . If you use navigation gestures, swipe up from the left bottom of the screen. Notice that the operator information in the upper-left will be replaced with an airplane icon. While in airplane mode, you cannot make or receive phone calls or text messages.
* When Airplane Mode is on, your phone's wireless functions such as Cellular Data will be default off. But you can still turn on and use Wi-Fi and Bluetooth if the airline allows that.
* If you are at abroad without a local SIM card, you can turn on Airplane Mode temporarily to avoid unnecessary roaming costs.
1.Restart your realme phone and test again.
2.Go to [Settings] > [Software Updates], then update your phone system to the latest version.
* Pictures, settings and paths might differ from those of your phone, but that do not affect the description in this article.
